UE recommended CSI settings

Abstract

Aspects relate to dynamically modifying channel state information (CSI) settings, such as CSI report settings and/or CSI resource settings, utilized by a user equipment (UE) in reporting CSI to a base station. For example, a UE may identify at least one parameter associated with a CSI setting and provide a recommendation to modify the CSI setting based on the at least one parameter to a base station. The recommendation may include, for example, an optimized configuration of the CSI setting or soft output, such as an uncertainty level or confidence level associated with the CSI setting. The base station may then select the optimized CSI setting based on the recommendation and provide the optimized CSI setting to the UE for use in generating and transmitting CSI reports to the base station. Other aspects, features, and embodiments are also claimed and described.
